Control and Safety

PID temperature control eliminates overshoot and oscillation. An independent safety circuit cuts heating if the plate exceeds 420 °C. HOT warning remains displayed after power-off—preventing accidental contact.

The Pt1000 sensor measures temperature directly in the liquid. Particularly useful for viscous samples where surface-only readings are unreliable.

Installation and Accessories

Direct mains connection: 200-240 V / 50-60 Hz. Probe support STIH-A04-001 sold separately. Brushless motor design removes the need for scheduled servicing.

Typical Applications

Thermally controlled chemical synthesis, large-volume solution preparation, isothermal processes. Routinely used in chemistry, pharmaceutical and quality-control laboratories.
